Bees are a vital part of our ecosystem and the success of the agricultural community. The U.S. Department of Agriculture estimates that bees pollinate 80 percent of our flowering crops, which constitute a third of everything we eat. A low or non-existent bee population would not only affect the produce we eat, but also the feed supply available to livestock.
The bee population is a waning one. In the winter of 2006-2007 a low hive population was reported to the USDA. With worker bee population losses spanning from 30-90% and an absence of dead bees, the phenomenon known as Colony Collapse Disorder (CCD) gained attention. Although these beehives still had a queen bee and young bees, coupled with an abundant honey and pollen supply, the hives would not sustain without the worker bees.
Why is CCD occurring? Researchers, along with the USDA, have focused their efforts on causes including:
- the invasive varroa mite (a pest of honeybees)
- the Israeli Acute Paralysis virus and the gut parasite Nosema, which are new and emerging diseases
- pesticide poisoning used for in-hive insect or mite control
- bee management stress
- foraging habitat modification
- inadequate forage and poor nutrition supply
Although not one particular factor is gaining more credit than another, some believe a combination of the above incidences could be creating CCD. Researchers are using four overall methods of study to determine why CCD is happening. They are collecting data from beekeepers, analyzing bee samples, conducting hypothesis-driven research, and instituting preventive measures to see the effect they have on bee health and habitat.
You can help the bees by providing space in your garden with flowering plants that support their need for nectar and pollen. Use OMRI Listed products to keep your garden chemical free and prevent bees from transporting chemicals to their hive. Provide a shallow water source to allow thirsty bees to drink without the danger of drowning.
